Yes, I only keep one roo, unless I am growing out a new one or got packing peanuts or hatchlings. I had the Uggo and Sumatra in separate coops, but they didn't bother each other when freeranging. My sumatra is really a super nice roo but he's 7 and getting up there.... I hatched some of his offspring this year with my mixed flock, we'll see how his boys turn out. I will probably keep one out. If there are no acceptable roos - I'll get another Faverolle flock or some more sumatra roos. I have had a few other long tale roos and they were not bad natured, which surprised me.
